$conn_identifier
, string $oid
, string $attr_name
)The cubrid_col_get() function is used to get contents of the elements of the collection type (set, multiset, sequence) attribute you requested as an array.
conn_identifierConnection identifier.
oidOID of the instance that you want to read.
attr_nameAttribute name that you want to read from the instance.
Array (0-based numerical array) containing the elements you requested, when process is successful;
FALSE (to distinguish the error from the situation of attribute having
empty collection or NULL, in case of error, a warning message is shown; in

cubrid_error_code()), when process is unsuccessful.
Example #1 cubrid_col_get() example
<?php
$conn = cubrid_connect("localhost", 33000, "demodb", "dba");
@cubrid_execute($conn, "DROP TABLE foo");
cubrid_execute($conn, "CREATE TABLE foo(a int AUTO_INCREMENT, b set(int), c list(int), d char(10))");
cubrid_execute($conn, "INSERT INTO foo(a, b, c, d) VALUES(1, {1,2,3}, {11,22,33,333}, 'a')");
$req = cubrid_execute($conn, "SELECT * FROM foo", CUBRID_INCLUDE_OID);
cubrid_move_cursor($req, 1, CUBRID_CURSOR_FIRST);
$oid = cubrid_current_oid($req);
$attr = cubrid_col_get($conn, $oid, "b");
var_dump($attr);
$size = cubrid_col_size($conn, $oid, "b");
var_dump($size);
cubrid_close_request($req);
cubrid_disconnect($conn);
?>
以上例程会输出：
array(3) {
[0]=>
string(1) "1"
[1]=>
string(1) "2"
[2]=>
string(1) "3"
}
int(3)
